Ive done it recently
4 bolts to remove the seat, unclick all the wiring harnessses. Pull it out (HEAVY!), turn upside down, pry up the plastics carefully with a vinyl prybar. Don't force things, there's several hidden screws and bolts holding things together.
Front plastic panel goes first afair. Few screws underneath.
If you have any manual dial-type controls or recline levers, take an eyeglass repair flathead pry out the center circle, should be a bolt underneath. Unscrew, then pull it off.
Remove headrest if doing the top, then pull up the plastic headrest holders (they come out of the pipe theyre in). Then unzip the rear, unclip the long clips using a long flathead screwdriver inserted into them parallel to the clip, and start pulling up gently.
You'll run into hog rings (cross between a staple and a nail bent into a loop) holding the leather, use 90 degree needle nose pliers to unsnap em. Its a pita, go slow and careful.
Repeat process backwards to install, use hogrings and straight needle nose pliers to install grabbing the new hog ring and just pressing (hog ring "pliers" that automate the staple feed usually won't fit/grab) OR use small heavy duty zipties instead. Have BOTH on hand before you start.
Have vinyl gloves to handle the leather.
When trying to get the clips into position, youll need a LOT of force and itll drive you crazy. You can use vinyl pry tools in the clips to help pull em together. A helper may be needed to get the zippers to come together.
Bottom is pretty much same, but simpler.
This will probably take you ALL DAY for the first seat. Have a good supply of beer and ibuprofen, you'll be sore and frustrated
